Problems solved by technology

Accordingly, many problems such as medical care for disabled persons and the elderly occur.
However, for some seriously disabled persons, all these devices mentioned above are not suitable.
The disadvantage of this method is that the upper boundary and the lower boundary of the eyeball often block by the upper eyelid and lower eyelid respectively.
In addition, its resolution is very low.
Thus, it is impossible to use it for long time.
However, sweat might affect the electrical signal read out.
So the signals become unstable and unreliable.
In addition, the electrodes are adhered on the skin of the user, so it limits its practical application.
But, it is not suitable for wearing such contact lens too long.
This kind of contact lens might injure the user.

Embodiment Construction

[0042] As shown in FIGS. 1 to 8, this invention relates to an eye-tracking driving system. An eye-tracking driving wheelchair is used as an example of the first embodiment of this invention. It mainly comprises a display device 10, an eye-tracking device 20, a calculating device 30, a controller 40 and a powered vehicle 50.

[0043] Referring to FIG. 1, this display device 10 is disposed in front of a user to look at. Usually, it can be a computer screen or a mini screen within a pair of goggles fitted on the user's head. In this embodiment, a 15-inch LCD (liquid crystal display) screen is used. A left turn mark, a right turn mark, a forward mark and a reverse mark are disposed on a left, right, upper, and lower positions of the screen. Similarly, there are four stop marks (not shown) disposed on four corners of the screen. In addition, the screen also shows the image in front of the user so that the user can control this invention easily. Or, display device 10 can be a foldable struct...

Abstract

This invention relates to an eye-tracking driving system, especially to an eye-tracking system controlled by the user's eye. It not only utilizes the unique eye-controlled method, but also avoids contacting with the user's eyes or skin. It is suitable for the disabled persons or the elderly so that they can drive a powered vehicle easily. The system mainly includes a display device, an eye-tracking device, a calculating device, a controller and a powered vehicle. This system can effectively capture the image around the user's eye and then precisely determine the pupil center. Based on the position of the pupil center, the power vehicle can be controlled.

Description

BACKGROUND OF INVENTION[0001] 1. Field of the Invention[0002] The present invention relates to an eye-tracking driving system, especially to an eye-tracking system controlled by the user's eye. It not only utilizes the unique eye-controlled method, but also will not contact the user's eyes or skin. It is suitable for the disabled persons or the elderly so that they can drive a powered vehicle easily.[0003] 2. Description of the Prior Art[0004] Due to the rapid development of medical technology, the life of a human is significantly prolonged. The death rate decreases. The averaged age of whole society gradually moves up. Accordingly, many problems such as medical care for disabled persons and the elderly occur. In Taiwan, the elderly was over 7% of the population in 1994. In September of 2000 the elderly (age above 65) became 1.9 million which is 8.6% of the total population. In addition, the registered physical disabled and mental diseased persons in the end of 2000 were 711,064 per...
